FDSN Membership

The membership of the FDSN is truly global and not dominated
by any one country or group. Members come from all continents.
Most members of the FDSN operate stations that are confined
to their national boundaries but several FDSN members operate
stations well outside their borders.

FDSN Membership includes 100 institutions in 73 countries.

Membership in the FDSN is open to all groups that operate
more than one broad-band station. Members agree to coordinate
station siting and provide free and open access to their
data (normally in SEED format). There is no charge for FDSN
membership.

The IRIS Data Management Center in Seattle Washington is a
repository for data generated by stations of the FDSN. Members
are encouraged to submit data in SEED format to the DMC but
it is not mandatory.

The following table lists all FDSN members.
